A new glucopyranoside from the leaves of Microsorium fortunei

A new compound, 2-hydroxy-4-[3’,5’-dihydroxyhexyl]phenyl-β-D-glucopyranoside (1), together with five known compounds (2–6), were isolated from the leaves of Microsorium fortunei. Their structures were determined by spectroscopic techniques, especially 2D NMR and MS data analyses. All of these compounds are phenolic glycosides and were isolated from this plant for the first time. In addition, compound 1 showed moderate inhibitory activity against...
